A wide variety of individuals -- usually ranging from drunk to stupid to both -- have invaded the pitching during football matches over the years, but I don't think any of them have ever done it while wearing a Pokemon backpack. Until now.
Early in the second half of Bayern Munich's big match against Borussia Dortmund, the invader ran right through the center circle as Bayern prepared to take a free kick from their own half. After the man did a knee slide to cheers from the crowd, he was escorted off. The incident would've been like a thousand others before, had it not been for the fact that he was dressed like a time traveler from 1993 in faded, high-water jeans and an incredibly ugly sweater tucked into those jeans and wearing Pikachu on his back. He wore a hat with an upturned bill that had the word "katze!" (cat) written on it.
The match went on to end in a 1-1 draw after the interruption. But more importantly, the world was saved from whatever was inside his Pikachu.
