>>59001505While I agree with most the assertions;
I could definitely see Infernape passing, like I'd imagine them as a troop swinging through a snowy forest with maybe some Monferno among them and any Chimchar's would be holding onto the Infernape's like a baby chimp irl. I could see them predating on like Piloswine and Snover, shooting Flamethrowers to both weaken the prey and force it to travel in a specific direction.
I can imagine a group of Greninjas just chilling around a pond, but if an opposing frog Pokemon like Seismitoad rocked up they'd gang up on it and attack its flanks until its driven off hurling Water Shurikens and striking it when its distracted with stuff like Feint Attack. It's more so the defensive cooperation rather than working together to find food as I'd imagine Greninja's could hunt down insects on their own.
I don't disagree with the assertion that Incineroar wouldn't pass although to be fair Tigers are solitary creatures in nature which kinda defeats OP's argument. I could definitely see Incineroar's being territorial but the main thing that breaks them for me is I can't imagine Incineroar caring for Littens and Torracats the way a tigress does.
Rillaboom I pretty see the same as Infernape, they'd definitely live in a troop with the smaller Thwackeys and Grookeys. Admittedly I wish Rillaboom had gender differences as I'd imagine the equivalent of the silverback of the group would play a much larger root drums. That's the main thing though is that I can see Rillabooms basically just chilling out in the jungle creating a cacophony of noise for social cohesion (think like how monkeys groom one another).
As another anon pointed out, I think Skeledirge would pass, just bunch of them chilling out at the water's edge, under mangroves and sunbaking. Admittedly I wouldn't imagine a Skeledirge doing a death roll to another member, but more so that they'd sort of vocalize their rivalry and slam against one another like elephant seals do.
