^I know this was from a looong time ago, before v17 was even released, but I just wanted to say that there's a HUGE difference between training with others and having their abilities influenced by Ise's dragon power, and stealing Euclid's Fake BG to combine with his own. It's majorly disrespectful and a huge insult to their pride, to combine the weaker Replica with the superior Original.

...Not even mentioning there's literally no use for it.
