The anime one will be harder to source clips but I do recall creatures being released as ‘energy’ then forming quickly from thrown objects. Will need to get back to you on that one!

Gen 1 Pokemon designs were straight rips of Dragon Quest monsters.

Arguably the Poke ball mechanic first appeared in anime such as Dragon Ball, Im not sure on any games predating Pokemon, but if they had patented it with the first games release it would have expired by now.

Nintendo will pull off some bullshit but they really shouldn’t have a leg to stand on.
