Companions are the flat Energy engine. Each world has a card banner. Keep one hero per slot and equip the highest rarity you own for the world you can farm. September estimates put Mythical companions around 3x Energy and Secret around 6x, which is the right shape for early tiers but does not match the later named table. Use the named numbers below when they disagree.
The full 42-hero list is on Heroes. Treat these as reported Energy values with limited confirmation, not independently verified in-game stats. Check the live card tooltip after a patch.
How the table scales
Inside one world the listed steps are Common, Rare, Epic, Legendary, then Mythic at 3x Legendary, Secret at 5x Mythic, and Broken at 6x Secret. Common itself doubles each world: +0.25, +0.5, +1, +2, +4, +8.
Examples that fall out of that pattern:
| World | Mythic | Secret | Broken |
|---|---|---|---|
| Alien Planet | Hidden Potential +6 | Saiyan Prince +30 | Broken Super Saiyan +180 |
| Titan District | Ace Scout +12 | Ace Captain +60 | Attack Giant +360 |
| Hidden Leaf | Slug Sannin +24 | Copy Ninja +120 | Sage Mode +720 |
| Sin Village | Boar Sin +48 | Lion Sin +240 | Demon Sin +1440 |
| Hunter City | Sword Dancer +96 | The Goliath +480 | Shadow Monarch +2880 |
| Pirate Village | Straw Hat +192 | Fire Fist +960 | Gear Fifth +5760 |
The reported September 14 Alien Planet ranking placed Hidden Potential above Namekian Warrior, then Strongest Human and Master Inventor, then Namekian Healer. That matches Energy order for the opening rarities and stops before Secret and Broken. It is not a six-world ranking.
Races, titans, and weapons are said to use their own Common-through-Secret tracks. Footage showed Secret race and titan units in the 2,000 to 3,000 token range before pity. Named rosters and a pity counter were not published, so they are not listed as wiki entries.
Avatars are a different slot
An avatar levels by defeating the NPC of the avatar you have equipped. An avatar you never wear does not level. Leave one strong avatar on during the farm. The 17.4x Titan avatar figure is from one filmed maxed avatar, not a base stat you get for equipping it at level 1.
What not to fuse away
The gap from Mythic to Secret is 5x on this table, and Secret to Broken is 6x. Once a Secret or Broken is a realistic pull, spending rerolls to polish a Mythic is the weak use of the currency. World Breaker at Broken tier 6/6 adds another 3x Energy on the passive layer. See World Breaker.
Hunter City's banner can Auto Spin during a raid for Sword Dancer and Surveillance Chief, which are also the mobs that drop Class Tree coins. Spinning them is both a card and a coin plan, documented in the Class Tree guide.
