The only way to get to his node f2p is to grind through.
My advise is to not buy character shards or gear for crystals. Use your crystals for energy refreshes, it's more efficient.
I assume you like the character and that's why you would like to have him. While his character can be good in some teams, I think it is important to get yourself familiar with all the other toons and squads in the game and which ones of these are better. With good squads you can progress faster. There are different routes you can take as a beginner and because this is a long term game it is good to have a plan so you know what characters you will be working on and use your roster as efficiently as possible.
There are lots of guides out there to help you. Because let's face it: in the beginning it is all very confusing. ?
I am not up to date which guide is the best now to follow but I am sure some member here can recommend you some.
