It makes me sad that not a lot of people seem to use Mecha Support in this game. There are a bunch of neat moves and cool sprites and fun flavor text most players don't seem to know about. I wondered if the reason for this might be because people just don't always know what mecha Mecha Support is going to give them and what moves it's gonna have. It's fairly obvious for the Robot Masters from 1-4, but what about the ones beyond?

The Mecha Moveset is generated based on the following ruleset.
1. The Mecha always gets their signature ability.
2. The Mecha will have a Support, Swap, and Break move, each for a different stat. For Dr. Light, it starts with Attack Boost, Defense Break, and Speed Swap, for Dr. Wily it starts with Attack Break, Defense Swap, and Speed Boost, and for Dr. Cossack it starts with Attack Swap, Defense Boost, and Speed Break. However, each time you summon the mecha, it will cycle through these, so your support moves are always changing. If you haven't unlocked all of these, it will try to find the next equivalent move.
3. The Mecha will gain up to four moves from the original Robot Master that are compatable with the mecha's core.
