FierceNon-hybridInGEN denies any part in the creation of this modified Tyrannosaurus rex, but admit to tracking its Map movements. Their specialists have noticed a pattern of unique territorial behavior. Strangely, this pattern sometimes includes the help of other creatures.

Boosts share 26 tiers at level 26, with up to 20 in each stat. Max fills the available budget.
Keeping 0 speed tiers (108 speed), these builds use all 26 tiers. Your current level, training and enhancements stay the same.
Taller bars mean a higher health × damage score. “Best” maximizes that score at your chosen speed, not your win rate. Abilities, opponents and speed thresholds can favor a different split. Select a bar to try it.
At level 26 with enhancement 0. Each ceiling puts as many available points as possible into that one stat; these are separate builds, not a combined maximum.

| Damage | 2,000 | 3,000 | |

To beat Mortem Rex, bring Shantrospinos, the best Apex counter. Use Evasive Wounding Charge, then Killer Instinct to win with about 100% HP left. Mortem Rex: Shantrospinos, Plateorex and Magnaraptor beat it at level 26, and it beats 313 of 494 creatures.
Each fight is played out move by move. Mortem Rex sees your move every turn and answers with its best reply, so a win here holds against perfect play.
The best 5 Apex counters. Every counter is in the full list below.
Mortem Rex picks Alert Fatal Strike, but Shantrospinos acts first with priority and stuns it with Evasive Wounding Charge, so Alert Fatal Strike never happens.
Mortem Rex takes 1,980 damage over time
Shantrospinos uses Killer InstinctPriority3,112 damageShantrospinos wins with 4,800 HP left (100%).
Both are simulated at level 26 with no boosts, enhancements or Omega training. If your Shantrospinos is higher level or boosted, this win only gets safer; if Mortem Rex is, it can turn the result, so check both builds first.
Full battle played move by move for up to eight turns. Quick estimate from a shorter six-turn screen; open one to play its full battle.

Hadros LuxApexWins33% HP left
ArctovasilasApexWins30% HP left
ConcatolochApexWins17% HP left
CeramagnusApexWins15% HP leftBoth creatures are level 26 with no boosts, enhancements or Omega training. Every unlocked move is available, including low-health variants, with delays, cooldowns, priority and speed order. The simulation applies armor, shields, dodge, cloak, critical hits, critical chance buffs and reductions, damage buffs and reductions, vulnerability, rend, healing, devour, damage over time, stun, daze, resistances and their reductions, cleansing, removals, immunity and counter-attacks. Daze stops the dazed creature's counter-attacks.
Stun, dodge and daze chances are counted as weighted outcomes, not sampled, and speed ties are split evenly. Critical hits count at their average: every hit adds its critical chance times the extra critical damage, so the damage shown in a battle includes that average. Each turn shown follows the most likely roll. Each battle is a fight to the knockout between these two creatures, so moves that swap the user out (Retreat, Rampage and Run and the like) are not used while another move is ready, and a win that can come sooner is taken sooner. Swapping, swap-in and escape abilities, taunt and flock damage limits are not modeled.
Every non-Omega creature is first screened against Mortem Rex in a quick estimate: up to six turns with a smaller search. The strongest candidates are then played out in full, up to eight turns, and any creature in the full list plays its full battle when you open it. A full battle can disagree with its quick estimate; the full battle is the better guide.
Battles are simulated at levels 26 and 35. When the build above is set to another level, the nearest one is shown and labelled.
These are simulated results, not guaranteed wins. A critical hit that lands, or one that does not, can change a close fight.
