So lemme get this straight

Pikachu, the Mon that's been there since the very beginning, doesn't get a "battle bond", but a ninja froge, whom Ash met some odd years later and don't even know in a fraction of the time, forms such a special connection, he gets his own (what essentially amounts to) unique mega. Getting a massive boost in battle potential.

That's either very gay or very dumb. Most likely both, though.
