Reaperspawn, huh...? Looks like Freddy Fboy may be needed after all. Dunno where he went off to, though.
Unless something went wrong, which I'm VERY certain hasn't, the Omni-Meme should be back in Cranky's hands by now, which means the Anti-Devil Hallow probably ain't gonna be as effective, but even then I'm most likely not gonna require it.
Well, while I'm here, may as well get some patch notes out of the way.

==PATCH NOTES==

=ELEMENTAL PROPERTY CHANGES - CHARACTERS=
Each member of Team Aeon has been given a set of elemental Weaknesses and Resistances unique to each member. I'll let y'all figure out these on your own, but here's change one in particular that I wanna highlight;

REMOVED TYPE_IMMUNITY {[Explode], [Wind], [Water]} FROM ENTITY "Trimarc"
Dude had like six Immunities beforehand, and Explode's pretty common last I checked. Also gave those punks from Singularity some tweaks to their Elemental Properties as well, though they haven't shown up on my radar for quite some time.

=MOVE CHANGES=
REPLACED TYPE_COPY OF MOVES {[Hallowed G-Cannon], [Hallowed Sigma Voltage], [Hallowed Omega Rocket]} WITH TYPE_ANTI-DEVIL
Since Artificial Types are a thing now, there's no reason to keep these as Copy-type. Speaking of which...

Anti-Devil: An Artificial Type/Element created by Rhys, specifically to counteract Beta Devil's (at the time, and probably still) evil machinations.

RENAMED MOVE "Hallowed G-Cannon" to "Hallowed Vanishing World"
This name change is to make the BN reference a tad more accurate. After all, G-Cannon is when BassGS summons Gospel's head to breath fire at you.

REPLACED TYPE_SHADOW OF MOVES {[Astonish], [Confuse Ray], [Ominous Wind], [Phantom Force]} WITH TYPE_PHANTOM
ADDED TYPE_PHANTOM TO MOVE [Shadow Ball]
REPLACED TYPE_NEUTRAL OF MOVE [Disarming Voice] WITH TYPE_SOUND
ADDED TYPE_STEEL TO MOVE [Steel Roller]
Yeah, I think that's about it. Hopefully I can stay active for more than like a week straight.

And that takes care of wave 20.
There don't seem to be any Cosmic Shards here, and I'm pretty sure nobody important saw me, 'cept maybe a midboss or two. Looks like this was a waste of time so far.
In fact, I don't think anyone important even heard what I said before I started impaling them with mental bamboo. Perhaps I should find higher ground or a more populated area, that way I can try again. Prolly gonna need to write a new evil speech in the meantime...

Derivative Aeon prepares to walk off, but stops.

Might wanna leave a note, actually.

Derivative Aeon uses some Venomous Plumes to write a giant message in the ground that reads "DERIVATIVE AEON WAS HERE FIRST, FOOLS". THEN he walks off.

Derivative Aeon uses a Bamboo Mirage, clearing out the 17th horde of mooks to come at him thus far!

Wow, I knew you guys were pathetic, but this is ridiculous! None of y'all have given me ANY trouble, even on wave 17! At this point, I'm practically being MERCIFUL by beating you up now before you meet a more painful end!
Honestly, blowing yourselves up would practically lower my chances of victory. That's how weak you cannon fodder are.

---

Move Name: Bamboo Mirage
Type: Nature/Mind
Description: The user sprouts illusory bamboo shoots from out of the ground that skewer opponents, dealing damage in a wide range, and with a 12% chance to inflict Confusion upon hit!

Somewhere near where Lambda Wind is (if he's still in the area), a voice can be heard...!

(???:) Well, ain't THIS the textbook definition of the first level in like, half of all video games!

Suddenly, the same childlike figure from before ignites a nearby set of trees to create a flaming background, thus topping off his dramatic entrance!

What's up, slords!? The name's Derivative Aeon, and I'm here to kick everyone's es up and down and all around!
Y'all better get ready to drop like FLIES, fools!

Derivative Aeon then summons a Venomous Plume to torch the nearest person!

---

Venomous Plume
Type: Flame/Toxic
Description: The user spawns a toxic blast of flame at the target's position, dealing damage with a 30% chance to inflict Poison! The infliction rate is doubled upon a critical hit.

In an icy, mountainous area not too far from Gear Plains, a small, childlike figure stands, obscured by a blizzard, though not bothered in the slightest by it.
(???:) Cosmic Shards, huh...? Well, now I know what the four objects permanently lodged in my head are.
(???:) Apparently there's a whole assortment of these things, too...! I bet I could stir up some MAJOR with 'em!
(???:) Maybe THIS can alleviate my endless boredom...!

(OOC: Now, Ch4s3, perhaps it's a new concept to you, no offense, but most of us like to put a bit of effort into our posts, including proofreading to make sure our grammar and spelling are on point.  This means posting ain't exactly gonna be instant. But I'm not gonna clog up the thread with an argument that doesn't need to be on the thread itself.)

Through a bunch of very sneaky stealthy maneuvers, Legacy Aeon and pals manage to reach the back door of the place without any issue. Right after sneaking in (and making sure to lock the back door of course, AND making sure nobody was following or watching them), Alternate Aeon speaks up.

Alright, now what the crap are we supposed to do?

---

*Would've gone with something like a mixture of the colors for Space, Laser, and Crystal for Mind's type coloration, personally, but since custom type bubbles ain't a thing, guess that means I'm sticking with Laser.

A certain alien robot with wearing suspiciously familiar armor is sitting at a computer screen, reading up about this new worldwide law against vigilantism. He's also taking a look at the letter addressed to him detailing what's going on.

Mother of , I hate this planet.

Shion dodges to the side, and attacks with an EleFang1! Then, Shion charges their buster whilst waiting for the Custom Gauge to fill!

---

EleFang (1 = 80, 2 = 110, 3 = 140): (Elec) The user conducts forked, piercing lightning bolts, attacking the column in front as well as the rows on both adjacent sides.

I'm back from being AFK, Shion. Got myself something to drink. What's up on your end?
Oh hey, Tsuba! Just fighting these viruses I haven't seen before.
"McCleavers", huh? Didn't know these could appear in Mugen 2. You want I should send something over?
Go ahead, fighting 'em's gonna be much more tedious otherwise!
A'ight, let's get this over with.

Shion shoots a Wtrhose1 at the already-damaged McCleaver (gonna call it McCleaver A from now on), then another at McCleaver C!

---

WtrHose (1 = 60, 2 = 110, 3 = 160): (Aqua) The user fires a piercing stream of water down the row.

Shion dodges to the side, and takes the opportunity to unleash a charged shot at a second McCleaver!

Ooh, I haven't fought one of these before!

Shion starts by shooting one of the McCleavers with their buster over and over!

Shion, still bored out of their mind, walks up to Curtiss.

Hi! You know where I can find an incident? I'm bored outta my mind, and the viruses around here are getting monotonous to fight as of late!

...Eh, guess we could hop on the net and see if there's anything going on.
Finally warmed up to the idea, huh?
Meh, I don't exactly have much to do, so let's go with that.
Tsuba heads over to his PC, and doesn't even bother with some overly flashy pose.
Just... Get in there already, Shion.EXE.
Tsuba jacks Shion in, and slumps into his swivel chair.


Now then, if I were an inciting incident, where would I be...?
Dunno. There's probably some juicy info on the Square's BBS.
...You DO remember where that is, right?
Nope!
Just keep following that gray road or whatever, you'll probably find where you gotta go.

The fireball barely did a thing to Fedora Ghidorah, who retaliates with some more Gravity Beams!

...Hold on, if one of Trimarc's summons is here, then where's the man himse-

OH HELLO THERE

Oh there he is, and he's even got his Rawkit Lawnchair equipped, and is firing rawkits at Rodan DS!

---

  The Neutral Orb, you ask? Well, newsflash, Darksider; there ain't one.
  Neutral is, in essence, the the lack of any elemental energy whatsoever. Even if an orb for it DID exist, you'd just be stealing everyone's inability to have elemental abilities, which would defeat the purpose of you collecting elemental MacGuffins in the first place.
  ...Say, I'm pretty sure I wasn't done killing you cowards to death, last I checked!

Rhys then uses Safeguard, followed by a MindCharge!

---

Move Name: Safeguard
Type: Shield
Description: The user creates a protective field around all allies that prevents ailments for 5 turns.

Move Name: MindCharge
Type: Mind/Weapons*
Descripton: Increases the damage of the user's next Special (non-physical) attack by 150% of what it would usually be!

*For more information on Artificial/Fake types such as Mind, refer to Page 109, Post 8. Before you ask, there aren't any orbs for these types, either, as they aren't natural.

However, a trio of Gravity Beams strikes Rodan DS!

  *Showa era Ghidora noises*

(Battle Music | King Ghidorah (Godzilla: Monster of Monsters! (NES))

Fedora Ghidora then starts flapping its wings to produce galeforce winds to blow Rodan DS away!
