Seeing how we have quite a few characters who bring along another friend to help out in combat, I’ve started to think how they can be effected by regular gameplay mechanics. And by that I mean, what roles do these summoned characters have?
As of this post, the only summoned characters we have in game are:
- Megabot (via Hiro Hamada)
- Rajah (via Jasmine)
- Sven (Kristoff)
- Beaker Clones (Dr. Bunsen Honeydew)
I took some time experimenting in levels that have the Hunter class of enemies (ones that specifically target a certain role with spider webs to Stun, else they otherwise attack normally), to see who they do and do not target, and have discovered the following:
- Rajah and Beaker Clones count as Damage units.
- Sven counts as a Support unit.
I have yet to learn what kind of role Megabot is since I usually defeat the enemies by the time Hiro brings him into play, but if anyone knows via the Hunter class of enemies, I’d be happy to learn! 
Otherwise, I hope this topic helps shed some light on teambuilding and stuff like that~
