He's just so <3 Something about how he lives with his complicated contradictions
Thinking about all the Raphs and their deep seated fear of scaring or hurting the people they love, and how Grid's super strength makes him even more capable of doing that and thus even more at risk and how Sliver's judgment and the public eye put even more pressure on him to so, so carefully toe the line at all times.
Sliver in the comic saying, "We have been unable to max out his strength," and thus Grid always lives in some level of tension and uncertainty, not knowing his own limits. Sliver training him and his brothers by fear tactics and survival instincts -
(Clamped and bolted to the table with the drill, Sliver saying, "You must get out of this if you want to live!" And the voiceover: Sliver's aggression scared us. But we thought he was doing what was best for us.)
- But the training is so backwards because Grid isn't allowed to act on simple aggression or fear or survival instincts out there or anything could happen. What if, what if, what if?
Thinking about this Superman quote: "I feel like I live in a world made of cardboard, always taking constant care not to break something, to break someone; never allowing myself to lose control, even for a moment, or someone could die." And how deeply Grid can probably relate.
How effortless it would be for him to kill someone if he gives into that famous Raph temper for even a moment and he's not a ninja who can vanish anonymously into the shadows afterward. It would be out there for the whole world to see, it would damage his whole family's reputation by extension.
Thinking about the times I've been in my turtle suit and little kids have wanted to come up to me but then they get scared and shy away and hide when I'm just 5' 6". How much more often Grid probably has to deal with that being nearly seven feet tall (and taller.) Something about the concept of gentle giants but by the nature of his work and his home life, he can't be. But with no upper limits, what could he become?
He loves his work, he loves the fight! But he can't love it too much or what if he goes too far and people fear his aggression as he fears Sliver's? What if they get the wrong idea and think what he loves is the destruction rather than the defense?
People judging him by appearances, because people always do. He's probably the automatic fall guy everybody is most likely to point at with accusations of property damage and collateral damage and using too much force and carelessness and etc. etc. etc. out in the field. The biggest target by nature. Made to feel like he's scary. Made to feel like he literally doesn't fit in. Made to feel small for taking up too much space. Made to feel like he's too much or not enough.
It's all of Raph's characteristic struggles with self-control and self-worth and the fear of being his own - and his family's - worst enemy, amped up to as yet unknown limits, put under a constant spotlight, constant pressure, with no real parental guidance or support - with the "guidance" actively worsening it, with the parent being his family's worst enemy.
BUT HE STILL MANAGES TO DO GOOD!
All the torture and manipulation and betrayal and loss of trust, it was all perfectly stacked for him and the team to give in to feeling lost and purposeless but they don't! He doesn't! He's the one who makes the vow to the city on behalf of the team that he and his brothers will not rest until they've defeated the evil!
Sliver tried to instill survival by fear but he survives by doing good! And that's the real showcase of his boundless strength! AAAAAAAAAA
