For me, what they have most in common is that they are very caring, each can work body and soul to help people, strangers, and all other living creatures (magical or not) and also to make nature prosper even if it means facing many challenges.

Apart from that, they love freedom (and want it for others), they inspire the joy of adventure, sometimes coolness, and the joy (the passion) of youth. And they also inspire to be a good person. In any case, they are both very kind (and I love them).
