Baymax looks down at Tadashi as he waddles up to them helping him and Abigail up to their feet.
He looks to where he shoot Hiro.

" Oh dear "

Was Baymax's only warning as a huge piece of rubble was thrown at them only to be caught by Baymax and set to the side but is was a decoy as Hiro's nanobots come rushing hitting Baymax in the chest throwing the robot back only to catch the robot in the air and whirl him into another ruined building. Baymax recovers from the blow getting to his feet only to lunge at Hiro using the thrusters to get closer to Hiro. Hiro's body language told Tadashi he was shocked to see Baymax coming at him at a alarming speed. Hiro rises his hand sending a wave of nanobots at Baymax sending the robot in a different direction.
Baymax quickly recovers and fires his right fist at Hiro the nanobots move to form a shield but Baymax's fist smashes right through the nanobots like they where a paper thin wall hitting Hiro in the chest.
Hiro back slams into a wall the fist returns to Baymax as he starts to march up to the now downed Hiro.
Hiro gets to his feet but he stumbles falling to his knees he hears Baymax coming but can't control the robot to stop it was immune to his abilities.
Hiro looks up at Baymax now who was standing over him Guess Hiro has to use plan b.
Victor wondered how could Cain be this strong he was able to keep all four them at bay and control Hiro and Kyle like trained dogs.
Kyle came out form the shadows striking Yama with a shadow like staff.
Callahan was having no easy time with all the mechanical animals either and honestly it was draining him of all his energy. he was lucky to send Abigail to help Tadashi cause who knows how those two are holding up against Hiro. he looked to see that Gogo and Honey managed to kill one of the one of the raptor units and now where dealing with the Omega unit while Kat kept Alpha that was till she jumped on to the Alpha's back biting down on it's neck and twisting it killing the Alpha. Callahan shifted to the left as a mechanical tiger jump past him only to get fried circuits as he shot the thing up with electricity.
He let's out a sigh as he goes to help Keri with the rest of those blasted mechanical animals Hiro so happily had to make for them.
Fred was not doing so well with the wyvern unit it kept on getting the upper hand on the fight till Wasabi came in with his blades drawn and slashes it across the face causing it to screech as it pulls back a few steps only to get slammed into by Fred knocking the mechanical beast over. The wyvern unit gets to it's feet as shoots a blast of plasma at the two only for Fred to quickly shift human dodge the on coming blast then shift back to kaiju hitting the wyvern in the chest sending the unit flying till it gets impaled by a thick pole the wyvern's eye start to dim till the life fades from the eyes.
It was just Victor, Yama vs Oni and Cain. Sure Yama was a huge man but dang he sure could stand toe to toe with Oni who kept getting caught off guard by the man's moves Victor on the other hand was having to go on the defense with Cain who kept using his ability to teleport that's till he had an opening with Victor from behind him but got blocked by two flaming katanas. Cain looks to see Vivian who kicks him to by the side with a round house kick knocking him back a few steps. Vivian looks back at her farther who nod his head as they take a fighting stance as Cain disappears only to appear between the two who attack him.

Hiro pulls his hand back and then quickly punches it forward sending a sharp edged nanobot tentacle that hits Baymax square in the chest.
Baymax eyes widen in shock at the attack from Hiro as his vision begins to fade as he sees Hiro walk up to him.
Hiro stands over the now fallen Baymax who's eyes close but Hiro's face fall with shock as he lift his hands to his head pushing his fingers through his hair. Tadashi and Abigail run over only to see Hiro fall to his knees in front of Baymax the nanobots pull back from Baymax's chest to Hiro who swipes his hand to the left in a quick hard motion.
As Tadashi and Abigail moved closer to Hiro and Baymax they could hear muttering from Hiro who now had a quivering voice with the hint of sadness and guilt.

" No,no,no,no, come back buddy I need you, you can't leave me now, come on "

Hiro yells the last part as he crawls over to Baymax's side.
Tadashi couldn't believe it Hiro was back but it took Baymax's life to bring the boy back to his senses.

" I didn't mean to I….couldn't stop, please Baymax come back "

Tadashi was close now to where Hiro turned to face them still looking at the ground. Tadashi could see tears falling from the bottom of the kabuki mask.

" My fault he's dead Tadashi…it's my fault "

Tadashi shook his head at Hiro.

" No it's not Hiro, Cain made you do this not you "

Hiro head shoots up as he looks at Tadashi.

" Cain did this ? "

Both Tadashi and Abigail nod as Hiro takes the mask off and looks at the direction where Cain was.
Hiro gets to his feet as he pulls the mask off letting it drop to the ground which shaders in multiple pieces.
Tadashi takes a step back in fear cause in Hiro's eyes was pure hate and rage. Hiro bares his teeth as he narrows his eyes in that direction.

" Hiro ? "

All the nanobots move toward Hiro which cause Tadashi to look at Hiro with worry that's when they hear a load bang looking to see that the nanobots had dropped silent sparrow and where now moving toward Hiro.

" I'm going to kill him "

Tadashi looked at Hiro with fear now as he tries to stop him but he gets grabbed by the nanobots and tossed by side Baymax.

" Stay out of my way "

Hiro growls as he move with a huge swarm of nanobots behind him.
Tadashi watched in horror as Hiro disappears wondering what kind of monster he just released on Cain.
