Hello, 4 month in player here. Thanos is not hard to obtain once you get a couple of decent characters, the problem is he is a very big resource sink. I understand you really want him, and yeah, he is worth it as he is powerful but if you are just starting, you'll need to give priority to other, cheaper, good characters who'll allow you to start clearing content. Once you unlock Thanos, you'll feel the temptation to start giving resources to him but really, that's a waste. Once you can easily clear most content daily, then go ahead and start working on him if you want!
You’ll have to beat his world boss 20 times to unlock him and then rank him up using Black anti matter, chaos norn stones, gold, and bios (other stuff too but those are the main materials). He is one of the hardest / grindiest characters to obtain and rank up so please understand it’ll be a LONG time if you just started playing
