Really fantastic cartoon, my favorite in cartoon category. The best cartoon online? This is an answer that has changed many times in my life and will probably change more often, but for now, Eon Kid This cartoon literally has everything. This is a cartoon you can watch online with any crowd of people, and everyone will enjoy it at least a little. It is a cartoon that truly knows what it is and wastes not even a second in conveying what that is. I never expected anything from this animated before and I blew my mind. It's taken me multiple rewatches and a lot of hours on the wiki to understand everything. After watching, I really liked the mix of feelings. I have not found Eon Kid cartoon full elsewhere so I uploaded it here, you can watch this cartoon online for free now.
