which is strongest between leone and Aquario???
It depends on the track and bottom that you are using for Leone and Aquario.
You did not need to make a new thread (which would be in the wrong forum anyway), just to ask one question. Questions about beyblade should be asked in the Ask a Question, Get an Answer thread.
We can't really tell you what one is better unless you give us what type of Track and Bottom you are using for the beyblade, and yes it is in the wrong forum, please think carefully before you post
