How Enemies Work in Tower Defense Simulator
Tower Defense Simulator splits its 75-enemy roster into two kinds: 62 normal enemies that appear in regular waves, and 13 bosses that show up as tougher, named threats at set points in a match. Every enemy carries a health total and a speed rating — speed is reported here as the wiki's named tier (for example "Below Average" or "Slightly Fast") alongside its numeric value, since raw speed doesn't map to a single fixed number across every mode.
Many enemies also carry one or more immunities or defense modifiers, shown on each card when the wiki records them. The most common immunities across the roster are Bloated and Nimble, which show up on the majority of enemies and block towers whose effects rely on those statuses. Bosses tend to stack more immunities than normal enemies — several bosses on this list combine flat damage reduction (a "Defense" percentage) with immunity to Stun, Freeze, or Burn, which is what makes them meaningfully harder to lock down than a normal wave enemy of similar health.
Enemies are also tied to specific game modes. The modes represented across this roster range from early modes like Easy and Casual up through Intermediate, Challenge Trials, and Hardcore, plus themed modes such as Molten, Legacy Molten, Frost, Fallen, and Voidcore. An enemy can appear in more than one mode — its modes list on this page shows every mode the wiki confirms it appears in, which is why filtering by mode narrows the grid to only the enemies that actually spawn there.
Because health totals can differ between modes and difficulties for the same enemy, the notes field (shown when the wiki records it) breaks down the per-mode health values reported by the source wiki page, while the headline HP figure on each card reflects the wiki's primary listed value.
Data Source & Freshness
Every enemy name, health value, speed rating, and immunity on this page comes from tds.fandom.com, the community-maintained wiki for Tower Defense Simulator. We last cross-checked this list of 75 enemies on August 3, 2026. If Paradoxum Games adds, removes, or reworks an enemy after that date, it may take a short time to reflect here — check the individual wiki page linked from each enemy's source for the most current state.
