Genderbending is not trans.
If a character is genderbent then they become biologically the other gender with all their ups, downs and functions. They go from XY and XX to XX and XY and the changes are literally biological.
A man or woman going trans will never become a woman or a man respectably because biologically they are still XY and XX.
And most importantly they can't have offspring like genderbent characters can.
A man genderbent into a woman can get pregnant while a transed man can't because the man is still XY and not XX.
A woman genderbent into a man can impregnate women while women that transed into men are still women because biologically they are XX and not XY.
So no. Genderbending is absolutely nothing like transing and I will be extremely vocal about this even if the whole world will want me deader than dead. I. WILL. STAND. MY. GROUND.
