Hopper is an anthropomorphic Frog from the same universe as Hoppy, and one of Garnet's friends.
Physical Appearance
Hopper is a Persian-green frog wearing a black cape with a hood, yellow mittens, and a pair of pale pink boots. She also carries a katana sword.
Personality
Hopper's personality is similar to Amethyst's, though more playful like Pinkie Pie. She sticks her tongue out a lot and exaggerates her sentences. She also constantly uses the term "hop" or "hopping" as puns in many of her lines. She also seems to take an interest in her power-measuring device as she seems to have it around a lot when it isn't broken.
History
Season 7
Hopper was the first to find Garnet when she came to her universe, disguised as an attacker, and dropping multiple bombs in order to start some training and to "get the blood pumping". She took note on Garnet's high levels of power, saying she could tell Garnet had been training. She began to get excited when told of Garnet's reason to be there, wondering what the object would be "this time". She happily went with Garnet and Hoppy, on the way running into Ringo before reaching Yonder Mountain. On arriving to Yonder Mountain, she used her device on the Foxman, warning Garnet that his power levels were off the charts. She was launched off the mountain shortly afterwards, crash-landing into the trees. That night, she joined them in training (eating a fly meanwhile as a snack), just before meeting Steven Universe, Blue, Peridot, and members of the Mane Six. She became extremely excited to see them, knowing them from Garnet's stories. When returning to Yonder Mountain, she and the others were teleported to the Ringo Zone. She attempted to stop Ringo, wrapping her tongue around him, but ended up electrocuted. She got out of the Ringo Zone alongside the others after the fight.
