I animated most of it when I was 14, but it came out when I had just turned 15.
I know there's lots of young people on this site. Young people usually aren't treated as seriously as they deserve.
If you're a young person, and you want to animate, there's lots of resources online for tutorials on YouTube on how to use Adobe Animate. You can get a free trial, or, if you're serious, a student subscription is $20/year. It took me about a month to make the Ultimate Showdown, but I had been practicing for a bit over a year at that point. I used a mouse to draw the Ultimate Showdown, but since then I've switched to tablets. You can get a budget wacom tablet for around $100~ USD.
There's also a free and open source programs called "Pencil2D" and "OpenToonz" which might be good to practice in. If you have an iPad, there are affordable options in the app store, and the iPad works as a tablet. (Edit: Someone in the comments said Pencil2D isn’t good. Just a warning!)
If you're serious about animation, and want a book that covers animation theory, the best I've read is "The Animator's Survival Kit" by Richard Williams. Here's a PDF.
I just wanted to put this out there, because I think young people are under-appreciated and don't get the support they need. Looking back on myself, it's sad I didn't get more support at that young age. If you're a pretty good artist and you learn to animate now, you'll probably have those skills for life (and the same applies for anything you're passionate about- music, art, writing, you name it.) There's lots of things trying to get our attention, between video games, TV, and all the rest. But nothing has been so rewarding over my life as building the skills that bring drawings to life.
It's worth it to put the time in.
I believe in you,

You pretty popular with even some group of artist make a remake of your animation. Congrats to be a part of internet history.

The remake was great. I was proud to see the influences they took. Much better animators than me!
