These are just two pictures of two different cartoon characters from two separate cartoons. On the left is Andy Arlington (Maya and Miguel/ PBS) and on the right is Richie Foley (Static Shock).
These two cartoon characters have nothing to do with each other, they just sort of look like each other, sort of, and are like each other in some ways. For one, they're white male cartoon characters with spiky blond hair and they wear green shirts with orange on them.
The differences, Andy is 10, Richie is about 14. Richie is a super hero, as "Gear," Andy isn't. Andy only has one full arm, Richie has two full arms. Richie also wears glasses, Andy doesn't, at least not right now, he could later in his life. Plus, it's a possibility that Richie is stronger than Andy and no doubt more powerful. It is unknown which of them is more athletic.
Andy is also a cartoon character more for little children and in a more peaceful cartoon. Richie is more for older children and in a less peaceful, more violent cartoon.
But pictures of these Richie and Andy combined is because they kind of sort of look like each other and could remind some people of each other if they look more closely.
Again, Andy and Richie have nothing to do with each other, but it's not to say fanfiction cannot be writen about these two or fanart cannot be drawn of these two.
A little more Trivia: Static Shock ended the same year Maya and Miguel began aring (2004)
