Need help finding a new character

I'm a peni main with an very aggressive playstyle. I don't want to be a onetrick so I#m searching for a new Character to play, preferably a tank. It should fit my tactical but also aggressive playstyle but shouldn't take too much time to learn because I also want to play peni and don't have that much time. But I have no idea which character to choose. Do you have any ideas?
