If superbot thought about the stage mashups enough to make sense then they will make the boss make sense. They thought about AP cap so they are smart enough to pick one of the best ideas for a boss and not some generic boss fight.
You really think they would just put you againts Drake as the final boss and his reason was "Hey guys just wanted to have party, im the boss fight an the winner gets to get a trohpy and a vacation to the beach!"
...Nah didnt think so
