I think we can assume from that that you would have to fight the Hulk, but it's hard to say for certain

Thread has been updated with all the latest information

One of Mandarin's entities is called "electro_blast" and the power it goes with looks like it would fit Electro.
Mandarin's only other entity is called "mandarin_tornado".
All this suggests that the projectile power that includes the "electro_blast" entity was probably originally meant for Electro.

Update on hela. There is no reference to her having a boss fight. After looking at the cut objectives and conversations she was likely going to be an npc in valhalla (maybe asgard). She has a temporary conversation.

kang the conquerer and annihilus had a 3d head like in xml2 which likely means he has a lost skin that hasnt been recovered

Agent X had objectives you would complete for him in levels such as mandarins palace.

MJ had a missing diary that needed to be found.

Frigga was a cut npc. Found a temporary convo for her in valhalla.
