...Couldn't finish this post last night since the website went down at this time, but anyway, normally battles like these go much more smoothly since my Mega Man is super powerful. Being hit with both Spark Shock and Bright Burst, I lost almost 3500 DEFENSE during the battle, hence the high damage taken even though my three stats are around 3000 each.

Robots like Turbo Man do not have everything they need to be fully playable, like their battle fields. You can, however, obtain their weapons. I actually had just asked this question myself in the Official Question and Answer thread. You can obtain a maximum of 30 robots as of this version. All other robots that are in are not playable.

@Shadowmnico Ah, I didn't even know I could get the weapons that way. Perhaps I'll go after the other robots after I finish the Fusion Star side quest, then I will have truly finished the game as is.

EDIT: This is great! I think I'll take a detour from the Star sidequest and get the other abilities I'm missing. I got Magnet Missile just now.

EDIT2: And I just got the weapon from my favorite RM, the Gemini Laser. I'm going to get all of the abilities if I can now.

I looked around where I could, though a search feature probably would have been helpful. I see people all the time, even the AI bots ingame, with weapons like Hard Knuckle and Gemini Laser. I do encounter these robots in the bonus missions, but I don't get any drops from them. Where would I encounter some of these extra robots to get their weapons? I kind of want to 100% the game as is right now, and I've collected about a fifth of the Fusion Stars so far. :P
