Oh really?Anything involving carnivorous behavior or slow and agonizing deaths are probably too graphic for Nintendo to include in the game.
Gorebyss- "Although GOREBYSS is the very picture of elegance and beauty while swimming, it is also cruel. When it spots prey, this POKéMON inserts its thin mouth into the prey's body and drains the prey of its body fluids." Note the GORE in its name.
Tentacruel- "TENTACRUEL has tentacles that can be freely elongated and shortened at will. It ensnares prey with its tentacles and weakens the prey by dosing it with a harsh toxin. It can catch up to 80 prey at the same time."
Yanmega- "By churning its wings, it creates shock waves that inflict critical internal injuries to foes."
So I don't think that graphic depictions are too much, as long as they are kept to a reasonable level.
"A vivacious Pokémon, SYCLANT can withstand the harshest of blizzards. They live in large groups, the most experienced commandeering the others."
"Despite their size, SYCLANT have a brazen spirit which spurs them to fight to the end. They can traverse mountains with the greatest of ease.
