Some easy online battle games for kids include AdventureQuest and Hero Zero. Both games are online fighting and adventure Flash games that feature character classes, battling enemies and completing quests for loot and upgrades.
AdventureQuest features class choices based on those found in traditional fantasy games, including dragonslayer, fighter, ninja, wizard and warrior. As of August 2015, players have the opportunity to defeat 600 unique enemies and collect 550 unique equipment items.
Hero Zero is mission-focused and includes both combat missions and time missions that yield experience points. Users apply experience points toward skill levels or new equipment. The game also includes customization options available in the in-game store.
